Why don't I have a custom title by now?!
This was posted in the Doom picture thread which is a bit a too obscure place for a bug report.
Unusual cock up during play testing of my custom map in PrBoom+:
i really need fix that misaligned bookcase, which somehow i missed.
Oh! and also there's the problem with one experimental action event that caused me to lose all my weapons (including fist), developing a weird ammunition glitch, not being able to activate anything, and an imp forever imprinted on the left of the screen (it looks like a giant one there though heh).
In Eternity, this provokes a crash.
Here is a link to the demonstration wad hosted on Mediafire.
As a heads up, when you start the wad, the crushing ceiling at the beginning will reduce your health to 40% or lower, this is required for the glitch to work. Just run straight through it, you don't need to stop under it.
A voodoo doll is required for this to work, but basically what happens is that, if you've taken 60% (or higher) damage, when you activate a crushing ceiling that destroys a barrel, and the splash damage radius is close enough to almost kill you via voodoo, but 'pushes' the voodoo doll into an invulnerability and megasphere power-up almost simultaneously, it causes this unusual glitch in PrBoom+. Nothing unusual happens in Zdoom (which is my default source port), but as for others, i'm not sure, i haven't tried.
As a note, i'm using PrBoom+188.8.131.52, which is the newer release. I'm not sure how this takes effect in earlier versions. Also if the glitch doesn't work straight away, try it again.
Edit: Also you can activate things when the glitch takes effect i've found out.
